GMC Acadia Catalytic Converter - Magnaflow - Direct Fit - `07-`08. This direct-fit, California Grade catalytic converter is designed as a factory-style replacement for 2007-2008 GMC Acadia applications and compatible GM vehicles.
MagnaFlow’s direct-fit unit (part 5451446) reproduces OE spun-body geometry using 3D metrology data to ensure accurate fit and function. Constructed with mandrel-bent tubing and corrosion-resistant 16-gauge 409 stainless steel, the compact, low-mass design helps maintain factory flow dynamics and thermal efficiency. A single laser fusion weld reduces potential leak points, and the converter ships with gaskets and hardware to simplify installation without reusing corroded factory parts. This California Grade unit has undergone CARB testing and is legal for sale in all 50 states when the vehicle’s Executive Order (EO) and Engine Family Number (EFN) match the converter’s CARB Executive Order.

If you have questions or need fitment help, call us directly at 512-982-9393 (TX) or 562-981-6800 (CA). We have two locations — Austin, Texas and the Los Angeles, California area — where we offer installation and customization services. Installation is permitted only when the vehicle’s EO and EFN appear on the converter’s CARB Executive Order. If you’re considering multiple items, contact us for shipping discounts. We install on premises at both locations.
